IoT systems need to deal with frequent network disruption and intermittent, slow, or poor quality networks. Minimal data costs are crucial on networks with millions and billons of connected devices.

Devices and Embedded Platforms

Devices and edge-of-network servers often have very limited processing resources available. Paho understands small footprint clients and corresponding server support.

Reliable

Paho focuses on reliable implementations that will integrate with a wide range of middleware, programming and messaging models.

“Under the Paho banner, open source client libraries for MQTT are being curated and developed; there are already MQTT C and Java libraries with Lua, Python, C++ and JavaScript at various stages of development. In this article we'll be showing how to use the Paho Java MQTT libraries to publish and subscribe.”

“How would you connect the information from a temperature sensor on a BeagleBone Black to an LED display on a Raspberry Pi and would your solution scale up to many sensors and displays? In this article we’ll show how MQTT and the Eclipse Paho project can let you answer that challenge.”

MQTT is a light-weight publish/subscribe messaging protocol, originally created by IBM and Arcom (later to become part of Eurotech) around 1998. The MQTT 3.1.1 specification has now been standardised by the OASIS consortium. The standard is available in a variety of formats.
